Application filed May 27. 1938. Ser-iai No. 236,71.

1T 'o all whom t may concer/a:

Be it known that I, Lotus Vvniror'rn, a subject of the King of GreatBritain, and a resident of New Rochelle, county of 1i/Vestchester, inthe State of New York, have invented certain new and useful improvementsin Coke-Oven Iron vl/fork, for which the following is a true and exactdescriptipn, reference being had to the accompanying drawings, whichforni a part thereof.

My present invention relates to the ccoiistruction of coke ovens andcomprises iin-- provenients in 'the iron frame worlr or sectionalizedarmor commonly applied to the sides of by-product coke ovens havinghorizontally elongated cokingchambers running transversely to the lengthof the battery, with door closed ends at the opposite sides of thebattery.

The general object of the invention is to provide a simple and effectiveframe work which will facilitate the operation of luting (sealing withclay) the joints at the margins of the removable doors closing the endsof the colring chambers, and which tend to insure joint loting of adesirable form, and to minimize the evil effects on the iron work andoven structure of sach failure of the joint seals as may be expected tooccur from time to time in regular operation.

The various features of novelty which characterize my invention arepointed out with partieularity in the claims annexed to and forming apart of thisspecification. For a better understanding of my invention,however, and the advantages possessed by it, reference should be had tothe accompanying drawings and descriptive matter in which I haveillustrated and described a preferred embodiment of my invention.

in the oven construction illustrated in the drawings, A represents themasonry oven structure proper which is formed with alternatehorizontally elongated eoking chambers A', and intervening ue heatingwalls A2. The ends of the eoking chambers are normally closed by doorsD, each of which comprises a metallic frame work D', and a body D2 oftire brick. At its sides each door is provided with ribs or flanges D3,which project beyond the margin of the door proper and abut againstportions C of metallic parts C commonly called flash plates, which coverthe ends of the hollow heating Walls A! and are interposed between themasonry ofthe oven structure and the vertical beams or buck stays B andB', which form major parts of the metallic frame work or armor of thebattery. The two buck stays Band B in front of each heating wall areconnected together by crossbraees B2, and the buck stays at the oppositeends of the heat ing wall are tied together by metallic tie rods runningtransversely to the length of the battery.

In so far as above mentioned, the construction shown does not eli-ilerfrom construction well known and in general use. The flash plates C, asshown, diier from those heretofore used in that they are formed at theiredges with outwardly projecting lips .or ribs C2. yThe ribs or lips C2are shown as forming outer extensions of' transverse flanges which alsoextend outwardly from the flash plate bodies, and at their .inner edges,are odset in the usual manner at C to,l provide seats for the innersides of the flanges D3 of the door. Preferably the transverse flangesof the flash plates and the ribs D3 of the door are shaped andproportioned to provide a comparatively narrow but deep tapered grooveor channel at each side of the door in which the luting or joint sealingmaterial H is packed. The lutng material H is ordinai-ily formed by claya' 'f 'iedwhile in a moistened mortar like com" ion.

` .The provision the lips C2 insures a lutafter charged With coal.

ing channel deep enough to receivev the proper vamount of luting.material and involves an economy in the use of the luting materialinasmuch as they form an effective check against the tendency of theWorkmen applying the, luting material to plaster the latterover aportion of the flat outer face of the flash plates C, Which is' commonlyexperienced With the construction hereto fore employed in which theflash plates are not-provided With the lips C2. The reduction in t eamount of luting material necessary to secure good join't seals, madepossible by the use of the present invention, 1s of value in that itreduces the labor required for the luting operation, and reduces theamount of the baked luting clay to be removed in breaking the joints andpreparing them for resealing when the coke is discharged from vthe ovenchambers and the latter. are there- An even more important advantageobtained by the use of the flash plate lip C2 arises from the fact thatWhen the luting joints fail, as they frequently do in use from thebaking and cracking of the clay as the coking operation proceeds, theissuing gas which ignites as it enters the atmosphere, is prevented bythe ribs C2 from wroking along the face of the flash plate, so that thegas flames do not come in contact with the adjacent b'uck stays. Theimpingement against the buck stays of the flames resulting froln thecombustion of the gas issuing through cracks in the luting materialitself, or other joint opening between the dried luting material and thead- I jacent liash plate surfaces, which is avoided with the presentinvention, has been a frequent source of injury to the buck stays ofcoke ovens as heretofore constructed. With the present arrangement thegas llames, resulting from leaks through the sealing material, can docomparatively little damage, and moreover the cracks themselves may beeasily located and closed, when serious, by the application of freshluting material.

Advantageously, the pair of flash plates C, at the opposite sides ofeach coking chamber, are connected in an oven of the type illustrated bya metallic part or lintel E above the coking chamber and forn'xing thetop portion of the door frame. Preferably the lintel parts shouldbeconnected to the flash plates b v joints having sufficient flexibilityor capacity for lost motion to accom.- modate the relative movcn'lentsof the two flash plates at the opposite sides of a coking chamberresulting from the thermal eX- passion of the oven structure. Theflexibility or l st1notion thus j )ermitted should. not be great enough,however, to permitany substantial movement of a lintel member relativeto the other parts of a door frame under the forces to which it issubjected in the apparatus, lies in the plane of. the lips C oftheadjacent Hash plates, and comprises pintlelike portions E5 at oppositeends, which are received in u notches C* formed in the "edges of theadjacent flash plate lips C. Each part E is also formed with lugs E6,which bear against ,the inner face of the corresponding flash plate lipsC when the parts are assembled. The notches C4 of the flash plates andthe pintle extensions E5 of the members E are so proportioned that themembers E may be swung into and out of place as indicated in Fig. 7. Theoven masonry is recessed as indicated at A4 to receive the body portionof the member E, and being further recessed as shown at A3 to/receivethe lugs E and an 'inner stiffening fla-nge or rib E7 formed at thebottom of each member E. Each member E also comprises a portion E2outwardly inclined from the body portion of the member and forming theupper wall of a luting channel )rovidcd between the member E and the rioroutwardlyextendinglip l)4 at the top of the metallic portion ofthecorresponding door D. Each member `E is formed, as shown, with lugs E3at the back of .the inclined portion E2 of the men'iber, and each lugris notched as indicated at E4 4to receive a locking bar F, the ends ofwhich' are also received in notches C formed in they transverse liangesof the corresponding flash plates C, the adjacent notches E4 and CG-registering when the member E is in its normal position. Each flashplate is formed with an inclined portion C5, which may be re* garded asan outturned portion of the corresponding flash plate lip C, and theseflash plate portions C lie in the same plane with the portions E2 of themember E in the assembled condition 'of the apparatus. Advantageously asshown appreciable clearance is provided between the vertical and topedges of the notches C'i and the adjacent edges of the member E andbetween the lat ter and the registering edges of the flash plates abovethe notches C4 to give the desired joint flexibility. After each membervE is put in place and secured by the corresponding bar F, the portion ofthe recess A4L above the member A is filled with moist clay or othersimilar luting material H. The material H is, of course, broken awayuand replaced by fresh material whenever a member E is replaced. The clayH`l prevents gas lcaka p c out of the oven chambers along the mem ersE.

The members lE \contribute to the formation of desirable joint seals atthe top of 'age resultin Those skilled in the art will understand thatthe expansion of the oven parts may cause appreclable relative movementsof the two flash lates C at opposite sides of the coking cham er. Forinstance on the expansion of the oven` brick work the flash plate at oneside of an oven door may move up with the upper portion of the brickWork with which it is in contact for an inch or so while the other flashplate may not lift at all or may move to an appreciably smaller extent.The expansion of the oven mayalso cause a greater outward movement` ofthe upper end of one flash .plate than of an adjoining fiash plate. Withthe described method of one side.

connectin the lintel members to the flash plates s'uc relative movementsof the upper ends of the flash plates may occur without resulting in anybreakage of the flash plates, lintels or connecting-means. lt will beundel-stood of course by those skilled in the art that afterathe initialheating up of the ovens is completedand thereafter from time to time vasrequired the recess A4 is repacked with clay to .eliminate gas leakageand to more or less firmly anchor the lintel member in place though notholding the lintel in place with sufficient rigidity and strength tocause breakage on normal subsequent relative movements of the upperendsof the flash plates. The flash plates CA adjacent the ends of thebattery are made with a single transverse fiange with lips C and C2 atbut Itwill be understood, of course, that the. fiash plate GA, shownA inFig. 3, is for use at the Ileft hand end of the side of the batteryshown in the drawings, and that a flash plate differing therefrom onlyin having its door frame edge reversed is employed at the opposite endof the same side of the battery. While in accordance with the provisionsof the statutes I have illustrated and described the bestform of myinvention noviT known to me, it will Abe apparent to those skilled inthe art that changes may be made in the form of the apparatus disclosedwithout departing from the spirit of my invention set forthin theappended claims, and that certain features of my invention may sometimesbe used with advantage without a corresponding use of other Ifeatures.
